It's getting to be a long time. Maybe now it's time to look at where we've been. If Pearl Harbor galvanized the nation in one direction, 9/11 galvanized it in many. Pro-war, anti-war, right, left, and scattered center.

Politicians and pundits have analyzed how and why. Now the psychologists are stepping in — and focusing on the impact of fear. Research finds the mere mention of death changes minds. The image of the Twin Towers exploding is a psychological supernova.
